摘要
测定了史氏鲟不同部位中17种氨基酸的含量，并对它们的营养价值进行了评价，结果表明，虽然史氏鲟各部位中常见氨基酸种类较为齐全，但不同部位中氨基酸总量和组成差异极其显著，氨基酸总量范围在3．26～105．０mg·g^-1平均氨基酸含量52．2＋36．9mg·g^-1。人体必需氨基酸含量略低于其他主要经济鱼类，但呈味氨基酸百分比介于鲷科鱼类和石首科鱼类之间。除了肌肉外，心脏、食道和鳔等部位中必需氨基酸和营养等级较高，具有综合利用价值。
The contents of 17 different amino acids in different parts of farmed Acipenser schrenckii were analyzed, and the nutrition degree was evaluated. The range of total amino acid from 3.26 to 105.0 mg/kg （wet weight）, and the mean value of different parts was 52.2 ＋ 36.9 mg/g. Althought the content of essential aminoacid in different parts of Acipenser schrenckii was retie tower man some other economical fish, the percentage of delicious amino acid was between Sparidae and Sciaenidae. In addition to muscle, the nutritional degree of heart, esophagus and fish glue also had relative high nutritional degree, and thus caused them compositive value for application.
